Hello!
I am trying to find the best approach for creating a distributed cluster based on the following specs:
-��������� 2 datacenters (close to each other and connected by fiber channel);
-��������� 2 storages (one on each datacenter);
-��������� 1 server on each data center
�
In an event of a failure of a single datacenter, the remaining datacenter must be responsible for assuring all services.
�
My approach would be to (I don�t exactly know if it is possible):
-��������� Present one LUN from each storage to both servers:
�� server A (DC A) - LUN A (STORAGE A)
���������� ���������������������������� ����� LUN B (STORAGE B)
��� �������server B (DC B) - LUN B (STORAGE B)
������������������������������� ����� LUN A (STORAGE A)
�
-��������� Create one logical volume on each of the servers using RAID1:
��� server A (DC A) - LVM A /mydata [RAID1 de LUN A e LUN B]
��� server B (DC B) - LVM B /mydata [RAID1 de LUN B e LUN A]
�
-��������� Configure a RedHat Cluster;
-��������� Put /mydata on the cluster;
�
Is this a feasible approach? Is there a better option?
